Liquid immersion cooling apparatus

Abstract

A liquid immersion cooling apparatus includes a box, a cover and a refrigeration device. The cover and the box form a closed space. The closed space includes a liquid storage space configured to accommodate a first coolant and at least one heat generating device and a gas storage space. The refrigeration device is located in the gas storage space. The refrigeration device includes a coiled tube, a liquid-cooled heat exchanger, and a cooling chip. The liquid-cooled heat exchanger is connected to the coiled tube to form a first circulation channel. The first circulation channel is configured to accommodate a second coolant. The cooling chip includes a hot end and a cold end, the cold end is thermally coupled to the liquid-cooled heat exchanger.
